專家說明

The special notes from the laboratories highlight the quality and rarity of this gem.
'Large rubies of top gem-quality are true rarities of nature... During the last couple of years, the supply of gem-quality rubies decreased... As a result, large, natural, untreated rubies of almost any geographic origin have become even more difficult to find on the market today'.
Gübelin Gem Lab, 22 September 2009
'The natural ruby described...possesses extraordinary characteristics and merits a special mention and appreciation. The described gemstone of 7.035 ct exhibits a well-saturated colour combined with a pleasant clarity. The stone has been spared to exposure of thermal treatment and its clarity and colour are natural'.
SSEF Swiss Gemmological Institute, 2 October 2009
